Question

How much greater is (−20x2+13x−4) than (11x2−13x−10)?

Answer 1

To find how much greater is the no.

we have to subtract them both...

$( - 20x^{2} + 13x - 4) - (11 {x}^{2} - 13x - 10) \\ \\ \\ - 20x^{2} + 13x - 4 - 11 {x}^{2} + 13x + 10 \\ \\ \\ - 31 {x}^{2} + 26x + 6 \\ \\ so \: this \: is \: the \: differene \: in \: between \: them.......$

hope it helps you....
